Intro

I'm a developer, technical writer, speaker and currently SRE.

I started my career as sysadmin, I worked several years configuring and maintaining bare-metal Linux servers. I've also closely
followed the arrival of virtualization in servers and later the process of containerization.

During this journey I acquired new skills that gave me the opportunity to work as a software engineer with PHP, Java and Ruby.
In addition I worked for a few years with pentest focused on web application security.

Over the years I've kept myself updated and embraced the DevOps culture, working later with Ansible, Docker and Kubernetes.
Currently I work as SRE which my main responsabilities are writing Golang system projects to keep the production Kubernetes
clusters running.

Besides being confortable with AWS, Google Cloud and Azure. I have also skills with cloud performance and Linux Kernel.

Remote2017 to 2018

I was responsible for designing and migrating the top Ruby on Rails applications that were previously on AWS to Google Cloud, using Docker and Kubernetes.

The automatic deploy pipeline that did not exist before was implemented using Codeship and Google Cloud Build. The end result of this work has ensured an immutable and scalable infrastructure.

I participated in the implementation of the entire PCI-DSS 3.0 process implementing some of the requirements with the team.

DevOps Engineer at Enjoei ;P

Remote2015 to 2016

One of the main challenges I had was to implement a new deploy pipeline for the production environment. I did the API migration that was previously in the AWS Beanstalk environment to Docker with Kubernetes.

Later I migrated the same API from Amazon to Google Cloud with GKE.

Another work I did was related to the performance of the main application, when migrating to Kubernetes and doing the tunning work in ElasticSearch impacted on the reduction of infrastructure costs.

Security Consultant at Initsec

I did a lot of consulting in cases where the focus was on finding vulnerabilities in Ruby on Rails applications (penetration testing).

I also worked as a DevOps Engineer planning infrastructure and migration between cloud providers using Ansible and Docker.

Software Engineer at Pagapramim

Remote2013 to 2014
